Mechanism and Mitigation Strategies of Asphaltene, Resin and Paraffin Deposition in Oilfield Equipment
Year: 2025
Type: article
Abstract: The article analyzes the existing technologies applied against asphaltene-resin-paraffin deposits (ARPD) formed in oilfield equipment and presents the results of scientific research conducted in the direction of developing more efficient methods to prevent these deposits.The formation of ARPD occurs due to the precipitation of paraffin, resin, asphaltenes and mechanical impurities present in crude oil onto the surfaces of equipment and pipelines as a result of changes in reservoir pressure and temperature.These deposits lead to a decrease in production, failure of technological equipment, shorter maintenance intervals and increased energy and material consumption.Since traditional methods such as cleaning with hot oil and steam are ineffective in deep wells, preference is given to chemical reagents, particularly paraffin deposition inhibitors and complex substances with depressor content.The article explains the composition and formation mechanism of ARPD, the role of surface-active components and analyzes the mechanism of action and advantages of chemical methods.As a result, it is shown that the development of new reagents based on synergistic principles is an effective and promising approach in combating ARPD.
